Installing and removing sources
Schedule
Every time you change a source that uses a different tuning mix.
Before you begin:
• Do a complete autotune (see “Calibrating the LC/TQ (Autotune)” on
page 48). If an autotune is not available, do a checktune (see “Calibrating the
LC/TQ (Checktune)” on page 44).
• If the tune report does not show good results, tune the instrument. If needed,
change the source to one that supports autotune.
